To all whomz't may concern:

Be it known that I JOHN A. SEooR, a citizen of the United tates,residing at Laporte, in the county of Laporte and State of Indiana, haveinvented a certain new and useful Improvement in Processes of Preparingan Explosive Mixture for Internal-- Combustion Engines, of which thefollowing is a specification.

My invention relates to a process of producing a mixture of fuel and airfor use in an internal combustion engine. In such engine are means forthe incorporation of a mixture of the fuel ingredients and a passage fortheir subsequent transmission to the engine or cylinder. The mixture mayconsist of air and any kind of fuel, or air, fuel and water and theparticular mixture with which I am concerned, is air, oil and water.These ingredients are commonly united by some apparatus in the processof introduction so as to produce in effect a mixture consisting of airand atomized oil and water. As these mixed ingredients pass along towardthe cylinder, experience shows that a certain quantity of the fuel, oilor water or both tends to be separated out of the stream of the mixtureby the impingement of the current on the walls of the passageway orvalves or controlling device which may be placed therein. My inventionrelates especially to compensating for this difficulty and it isillustrated by the particular mechanism which may be used to carry outmy process. Of course, various other sorts of mechanisms could bedevised,

l either automatically or hand controlled.

The particular illustration which I have se lected is that of an engineadaptedto be supplied with a mixture of oil, air and water and where thedifiiculties of separating out the liquids from the mixture current aredue to the throttle valve.

In illustrating this:

Figure l is a cross section through the carburetor with a firstreatomizing device;

Figure 2 is a detail cross section of the passage pipe with a modifiedform of atonh izing device; l

Figure 3 is a detail of an extension of the passageway and showing areatomizer at the intake valve.

The device of Figure 3 is intended to be used .in connection with thedevice of Fig-` ure l and the device of Figure 2; or 'any otheratomizing device could be substituted for either or' both of theatomizing devices shown in Figures l and 3, but a single reatomizingdevice of any kind could be used either near the throttle valve or nearthe intake valve or at any point between them. 1

and water nozzles and the engine, adapted to be controlled vby means ofthe lever'A.9 and link A10 from governor or other throttle controlledmechanism not here specifically illustrated.

B is an atomizing or re-atomzing sleeve inserted in the passageimmediately below the butterfly. This sleeve takes the form of amodified Venturi tube. The modification consists in that the tube is cutaway on the up-stream side of the point of greatest contraction so as toprovide a sharp annular knife edge B1 with a downwardly and outwardlyextending curved channel or reservoir B2, thewall of the Venturi tubebeing sloped upwardly from the bottom of the reservoir as at B3 to nallymerge into the normal Venturi contour. In order to illustrate the slightmodification the :normal Venturi contour is shown in dotted lines asiatB4.

The venturi B is integral with the flange C, and this flange may beinserted between the carburetor and the engine, and the carburetor webwill be protected against breaking by i'iller blocks C1, or washers,which.

take the strain of the bolts, and are the same A 100 rangement gives afinal atomization land mixing j ust as the mixture enters the engine,and thus we have a peculiarly Ihomogeneous mixture which leads topeculiarly satisfactory operating results.v

y Thus I have disposed two Venturi tube atomizers between the throttlevalve and the intake. Y

Referring to the device of Figure 2, the passageway A1 isV provided withan interior trough F which is arranged about the side ofthe passagewayand is provided with the edge G. Under certain conditions such a devicemight be operated more or lesseifectively' to atomize the liquid bycollectlng 1t 4as it flows down the side and then exposing it to theouter knife like edge of the trough which lies in the path of the movingcur# rentv of air or mixture. This is only d one to suggest thedifferent forms of atomizer which might be employed.

The use and operation of my invention are as follows The liquid fuel andthe water, although,

of course, the water might be dispensed with, are fed into thecarbureting pipes or chamber in the usual manner, being induced by therapidly flowing air current caused by the operation of the engine. Themeans not illustrated in detail, are provided, of course, forcontrolling the flow of both the liquid fuel and water. It will be notedthat the water and fuel nozzles ldischarge into the carbu-4 retor atdifferent points wherethe pressures are different'thus, of course,resulting, in

`automatic differences at the nozzle which being heavier than the air,it will be separated out by inertia and the air will go on carryingprobably a lean and unsatisfactory mixture and the liquid will rundownthe walls ofthe tube. This liquid will caught by the ledge in theventuri and the little annular reservoir formed 'by that-ledge will befilled up with liquid, and as more liquid comes down, it will overflowthe sharp knife edge. Asit overfiows, it comes into the direct path ofthe yair and it will be suddenly torn apart and atomized by such air.'

Experience shows that the diameter of this modified Venturi tube for thelower reatomizer must'be a little larger to get the same capacity, thanthe diameter of a norf mal venturi. This is probably caused by the factthat the effective diameter ofthe venturi is decreased by the thin filmof oil overiiowing the ledge all the way around, before this thin filmof oil has time to be broken up and carried away as part of theatomizing mixture.
